Найти массу дуги кривой y=x^2+4 от точки A(0;4) до В(2;8), если плотность в каждой точке её равна абсциссе точки.
Я считала по формуле:интеграл(от 0 до 2)(x*корень квадратный из (1+((x^2+4)')^2))
Это правильная формула?
Спасибо

Правильная.

Спасибо огромное

He looked through the doorway with his ears lifted high and his tail wagging as fast as it could. To his great surprise, he found himself staring at 1000 other happy little dogs with their tails wagging just as fast as his. He smiled a great smile, and was answered with 1000 great smiles just as warm and firendly. As he left the House, he thought to himself, "This is a wonderful place. I will come back and visit it often."
